Item Feasibility Analysis of Integrated Hybrid Systems of Wireless Sensor Networks and Conventional Networks(IIUM Press, International Islamic University Malaysia, 2011-11-06) Salami, Abdulazeez Femi; Bello-Salau, Habeeb; Hussaini, Mukhtar; Anwar, FarhatServices are the main driving force of the telecommunication industry. The rapid growth of the Internet led to the proliferation of a wide variety of services that allow application users to exchange information in different ways. In order to increase the benefits derived from the Internet (IP) based services, the IP Multimedia Subsystem (IMS) was developed to support new value-added services in wireless networks. The objective of the IMS is the seamless integration of wireless communication networks and the Internet. One of the most flexible and suitable network that can potentially integrate with the Internet is Wireless Sensor Network (WSN). WSN is essentially a network of collaborating miniaturized devices known as sensor nodes. The features of WSN are unique and different from other conventional networks. This is because WSN is typically a data-oriented network where sensor nodes are deployed and tasked with the responsibility of sensing a desired geographical area in order to gain useful information about the environment and report to the base station for further processing and analysis by the interested applications. Afterwards, these applications store the processed data for demand-based delivery of enhanced services to the end user such as the provisioning of context-based services to mobile phone users. These applications are customarily located in an area remote to the WSN and the governing network where such applications reside is usually an external network (e.g. IMS). Therefore, the challenge is to smoothly integrate WSN with IMS in order for the sensed data to be easily accessible to IMS applications or services. This chapter explores the major techniques that are employed for the seamless integration of WSN and IMS network. This chapter also provides practical design recommendations for implementing a presence-based WSN-IMS architecture. This proffered architecture will provide a general platform to applications and services that needs to access various types of sensed data from the WSN. This chapter also gives a systematic description of the key procedures for the integration of WSN with other conventional networks and most especially, the important evaluation criteria for assessing the state-of-the-art hybrid systems in this field is provided in this chapter.Item Practical Applications and Design Challenges of Wireless Heterogeneous Sensor Networks(IIUM Press, International Islamic University Malaysia, 2011-11-06) Salami, Abdulazeez Femi; Anwar, Farhat; Bello-Salau, Habeeb; Hussaini, MukhtarAs a result of the technological advancements in information and communication technology, the field of wireless sensor network (WSN) has witnessed rapid progress over the last decade. Customarily, a WSN is made up of a number of wireless networked low-power sensor nodes, each of which is designed with an in-built microprocessor, radio transceiver and limited storage, computational and energy resources. Nowadays, WSN are deployed in environments where conventional wireless networks operate, therefore heterogeneity is becoming an essential factor in WSN design because key design features like processing power, communication ability, sensing techniques, energy resources and computational capability have to be fine-tuned to adapt to conventional wireless network requirements and scenarios. By implementing a heterogeneous network of WSN and conventional wireless networks, the potential and performance of the sensor nodes will be greatly enhanced and most especially, the WSN will have the significant advantage of having a wider coverage area and adaptability for different types of applications. A lot of unique and interesting challenges arise when WSN is incorporated and enhanced with heterogeneity due to the demand to adapt and perform well with a number of other target applications. As a result of the aforementioned challenges, this chapter is motivated by demands from industrialists and researchers to investigate and bring out the feasible applications and design challenges of developing a reliable and energy-efficient wireless heterogeneous sensor network.
